iOS Objective-C Xcode - 如何开始播放风景视频

我正在构建一个应用程序来播放360视频 - 一切都很好！iOS Objective-C Xcode - 如何开始播放风景视频

但是，我希望视频仅在手机以横向为导向时才开始播放！如果在肖像中，它应该显示一条消息“请把你的手机放在风景中”，如果是的话 - 开始播放视频。 ..

任何人有什么想法如何实现这一目标？

这将是惊人的:)

谢谢！

按钮正确显示现在警报：

Video360ViewController *videoController = [[Video360ViewController alloc] initWithNibName:@"HTY360PlayerVC" bundle:nil url:url]; 

[videoController VRMode:true]; 

if (![[self presentedViewController] isBeingDismissed]) { 
    [self presentViewController:videoController animated:YES completion:nil]; 
} 
}

和警报被显示：

-(void)doSomething 
{ 

//Show Alert 

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Simple" message:@"Turn your device to Landscape." preferredStyle:UIAlertControllerStyleAlert]; 
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {

[alertController addAction:cancelAction]; 
[alertController addAction:okAction];

} 

-(void)doSomethingElse 
{ 
//Function Body 
//play the file

您是否在使用MPMoviePlayerController播放视频？ –

谢谢回复，不，我使用https://github.com/islate/SlateVideo360 但是，如果你有什么用MPMovie工作，我也许能使其与一个工作？ – tibewww

如果您正在演示视频视图控制器，你可以强制它是唯一风景.... – Lefteris

是的，所有你需要做的是创造一个UINavigationController子说LandscapeNavController，并把下面

代码LandscapeNavController.h

#import <UIKit/UIKit.h> 

@interface LandscapeNavController : UINavigationController 

@end

LandscapeNavController.m

@implementation LandscapeNavController 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
{ 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) { 
     // Custom initialization 
    } 
    return self; 
} 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
    self.navigationBarHidden=YES; 
} 

-(BOOL)shouldAutorotate{ 

    return YES; 
} 

- (NSUInteger)supportedInterfaceOrientations{ 

    return UIInterfaceOrientationMaskLandscape; 
} 


- (void)didReceiveMemoryWarning 
{ 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
}

现在提出的视频控制器，模式像下面提到

VideoController *controller=<INITIALIZE> 
LandscapeNavController *nav=[[LandscapeNavController alloc] initWithRootViewController:controller]; 
[self presentViewController:nav animated:YES completion:nil];

，并确保你的旋转设置应该是

此外，在AppDelegate.h定义

@property（assign）BOOL should旋转;

您驳回视频控制器前出示视频控制器和NO之前，上述属性应设置为YES。

而且在AppDelegate.m

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window 
{ 

    if (shouldRotate) 
     return UIInterfaceOrientationMaskAll; 
    else 
     return UIInterfaceOrientationMaskPortrait; 
}

注意添加以下代码 - 上面的代码没有经过测试，现在，如果你面对的问题平。

干杯。

声明属性为UIAlertController为：

@property (strong, nonatomic)UIAlertController *alertController;

你可以使用这样的代码：

- (void)viewWillAppear:(BOOL)animated { 

    [super viewWillAppear:animated]; 
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(deviceOrientationDidChange) name:UIDeviceOrientationDidChangeNotification object:nil]; 
} 

-(void)deviceOrientationDidChange 
{ 
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; 
    if (orientation == UIDeviceOrientationPortrait) 
     [self doSomething]; 
     else 
      [self doSomethingElse]; 
    } 
-(void)doSomething 
{ 

//Show Alert 

self.alertController = [UIAlertController alertControllerWithTitle:@"Simple" message:@"Turn your device to Landscape." preferredStyle:UIAlertControllerStyleAlert]; 
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) { 
     NSLog(@"Cancel"); 
    }]; 
    UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { 
     NSLog(@"OK"); 
    }]; 

    [self.alertController addAction:cancelAction]; 
    [self.alertController addAction:okAction]; 
    [self presentViewController:alertController animated: YES completion: nil]; 
} 
-(void)doSomethingElse 
{ 
//Hide the AlertViewController 
[self.alertController removeFromSuperview]; 
//Code to handle the playing of the file 
} 
-(BOOL)shouldAutorotate{ 

    return YES; 
}

编码愉快。希望能帮助到你。

嗨易卜拉欣，我补充说，在我的Viewcontroller.m没有sucess，它刚开始的视频肖像玩。。 ..我已经更新了我的ViewController.m中的代码原始questoin，如果它有帮助？非常感谢您的时间！ – tibewww

好吧，当我进入视图控制器时出现消息是:) 但无论如何，它只出现一个我已经点击到其中一个按钮:(？并使它一旦消失在ladnscape？它应该采取以下路径：当我到达我的视图控制器，我点击一个按钮，此按钮开始播放视频这个按钮的点击，如果用户是在肖像，它应该显示此消息，并作出。感谢您的全部时间;） – tibewww
